Sum, what CD would a car like mine typically have? Backing into it using your calculator, and my fastest run of 189 MPH, I would estimate between a .4 and .45. Does this seem correct?
So, my HP needs look something like this:
CD .4 .45 .5
HP for 189 MPH 482 535 587
HP for 201 MPH 571 635 698
This, of course, assumes my CD estimates are close!

Input Rolling Resistance ======> .024 <== (Note:
Input Car Weight =============> 5000
Input Frontal Area in Sq. Ft. ====> 24.00
Input Cd For Car Body Only====> 0.45
Input Velocity in MPH =========> 201
Body Drag Force = 1064
HP for Rolling Resistance = 37 HP
HP Needed for Car Body = 598 HP
HP For 4 Tires/wheels = HP
For this Speed = 201 MPH
Total RWHP Needed is = 635 HP
